STRIP-CUTTER.

To all whom it may concern:

Be it known that I, ALFRED J. Pmnon, a citizen of the United States,residing at Conshohocken, in the county of Montgomery and State ofPennsylvania, have invented new and useful Improvements inStrip-Cutters, of which the following is a specification.

The present invention appertains to means whereby sheet material such asleather, raw hide, and the like of any thickness may be cut into stripsof uniform width for any desired purpose.

The invention has for its object to provide a machine, which may bereadily adapted to material of different thicknesses and which may beeasily adjusted to out said material into strips of determinate width,the several parts being so arranged and constructed as to admit of theirinstant adjustment or ready separation for any desired purpose andaccording to existing conditions,

The invention consists of the novel features, details of construction,and combinations of parts, which hereinafter will be more particularlyset forth, illustrated and finally set forth in the subjoined claims.

Referring to the drawings, forming a part of the specification, Figure 1is a front view of a cutting machine embodying the invention. Fig. 2 isa perspective View of one member of the holder for the cutting blade.Fig. 3 is a perspectiveview of the other member of the holder for thecutting blade. Fig. at is a top plan View of the cutting machine. Fig. 5is a perspective view of a bracket forming a mount for an adjustable rodor bar. Fig. 6 is a transverse section on the line 6-6 of Fig. 1. Fig. 7is a view in elevation of one of the end-pieces. Fig. 8 is a detailsectional view on the line 88 of Fig. 6.

Corresponding and like parts are referred to in the followingdescription, and indicated in all the views of the drawings, by the samereference characters.

The cutting machine comprises like endpieces 1 and pairs of rods or bars2 and 3. Each end-piece 1 is provided with a central opening 4:, a pairof openings 5 near the lower edge, and a pair of slots 6 extending inparallel relation and in line with the openings 5. The end-pieces 1 maybe of any construction and are preferably of approximately circularoutline with their up- Specification of Letters Patent.

per edges flattened. The lower rods or bars 3 are connected at one endwith one end of the end-pieces in any substantial way and have looseconnection with the opposite end-piece. The upper rods or bars 2 passthrough the slots 6 and are adapted to move therein toward and from therods or bars 3, so as to vary the space between the two sets of rods orbars according to the thickness of the sheet material to be cut up intostrips. The lower rods 3 are threaded at one end into the openings 5 ofone end-piece and pass loosely through the openings 5 of the otherend-piece. Brackets 7 are provided for opposite ends of each of the rodsor bars 2 and each bracket is provided at one end with an opening 8 andhas its opposite end portion bent at a right angle, as indicated at 9,and formed with an opening 10. The openings 8 and 10 are reinforced upontheir outer sides by bosses in order to provide extended bearings. Theupper rods or bars 2 are arranged to operate in the slots 6 of theend-pieces and are supported in the openings 8 of the brackets or mounts7. One end of each of the rods or bars 2 is threaded into a bracket 7,as indicated in Fig. 8, and the opposite end passes loosely through theopening 8 of the opposite bracket, thereby admitting of the adjacentend-piece 1 and brackets sliding upon the rods or bars 2 when moving theend-pieces to vary the distance between them according to the width ofthe sheet material to be cut into strips. One of the end-pieces isrelatively fixed, whereas the opposite end-piece and brackets or mounts7 are adjustable upon the opposite end portions of the rods or bars 2and 3. Set screws 10 threaded into the bosses extended outward from theadjustable brackets 7 secure the latter upon the rods or bars 2 in thedesired adjusted position. Each end-piece is provided with a handle 11,which is threaded or otherwise secured in the central opening 1 of theendpiece.

The upper rods or bars 2 are adjustable toward and from the relativelylower rods or bars 3. This adjustment is effected by means of set screws12, which are mounted in the bent ends 9 of the brackets or mounts 7 andhave screw thread connection with the end-pieces. The upper ends of theset screws 12 are connected by a swivel joint with the bent ends 9, soas to turn freely therein. Upon turning the set screws 12 the bracketsor mounts 7 are moved with reference to the end-pieces 1 and efiect acorresponding movement of the rods or bars 2, thereby admitting of thedistance between the upper and lower rods being varied to suit thethickness of the material passing between the said rods.

Any style or type of cutter 13 may be provided for cutting the materialinto strips. The cutter shown consists of a knife blade and is securedto upper and lower holders, of light formation, each mounted upon a rodor bar 2 and 3, as indicated most clearly in Fig. 6. Each of the holdersconsists of complemental members 14 and 15. The member 14 has a recess16 formin a seat to receive the cutting blade 13. ne end of the member14 is provided with a threaded opening 17 to receive a set screw 18 andwith an opening 19 intersecting the opening 17 and extending at rightangles thereto so as to receive the rod or bar 2 or 3 upon which theholder is mounted, the set screw 18 serving to secure the holder uponthe rod in the located position. The member 15 has a projecting portion20 to enter the recess 16 of the member 14 and clamp the cutting blade13, as indicated most clearly in Fig. 4. The members 14 and 15 areformed with transverse openings, through which pass machine screws orfastenings 21, by means of which the members are drawn together so as toclamp the cutting blade between them. The upper and lower holders areseparable with the bars 2 and 3 upon which they are mounted. A guide 22serves to retain the outer or rear ends of the holders for the cuttingblade in proper position. This guide consists of a rod, which, as shown,is secured in a vertical opening formed in one of the holders and passesloosely through an opening formed in the other holder. A set screw 23threaded into an opening of one of the holders secures the guidethereto.

While the machine is specially designed for cutting leather or raw hideinto strips of uniform width, it is manifest that it may beadvantageously employed for cutting sheet material of any nature intostrips capable of being cut by a knife blade. The rods or bars 2 and 3may be of any length and by adjusting the distance between theend-pieces 1 the machine may be readily adapted to the width of thematerial to be cut. It is to be understood that theconstruction is suchas to admit of the rods or bars 2 and 3 being readily replaced by likeparts of different lengths according to the width of the material to becut into strips. After the end-pieces have been adjusted to the width ofthe material the distance between the upper and lower rods 2 and 3 maybe adjusted by operating the set screws 12, such adjustment serving atthe same time to regulate the distance between the holders receiving thecutting blade. The width of the strip to be cut is regulated by movingthe cutting blade 13 to the required distance from one of theend-pieces, the holders being secured in the adjusted positionbyretightening the set screws 18, which were previously loosenedpreliminary to adjusting the cutter. The piece of leather or othermaterial to be cut into strips is secured at one end in any manner, themachine having previously been fitted to the end to be made fast, so asto leave a portion projecting in the rear thereof to be secured. Afterthe machine has been adjusted to the material and the latter secured inthe manner stated the handles 11 are grasped and the machine therefrom.The distance between the upper and lower rods or bars 2 and 3 havingbeen adjusted to the thickness of the material it follows that saidmaterial is prevented from bucking, hence the strip cut is of uniformwidth throughout its length.

From the foregoing description, taken in connection with theaccompanying drawings, the advantages of the construction and of themethod of operation will be readily apparent to those skilled in the artto which the invention appertains, and while I have described theprinciple of operation of the invention, together with the device whichI now consider to be the embodiment thereof, I desire to have itunderstood that the device shown is merely illustrative, and that suchchanges may be made when desired as are within the scope of the claimsappended hereto.
